Title: Filter element for gas partic. as cigarette filter tip - uses contraction of gas passage to form condensate for absorption
IPC: A24D3/04
Filed: 1973-04-11
Abstract: Tubular filter element for gases in which the gas inlet leads to a cross-section where the area available for passage of gass is suddenly reduced very considerably compared with the cross-section being presented in the form of very small holes (e. g. 4) through which gas is compressed as filaments from which droplets of condensate separate on the outlet side of the holes to be trapped in the retention zone of an absorbent pad of spongy material just downstream of the reduced cross-section. The filter is used for filtering condensable pollutants from fumes and gases, particularly as a filter-tip element for cigars, cigarettes, pipes and cigarette-holders to filter out noxious substances from burning tobacco. The element, or tip, is very cheaply made but highly efficient.

Title: Local treatment system for moving strip - has independently actuated rotating local treatment stations for strip material
IPC: B41F13/02
Filed: 1974-04-26
Abstract: The arrangement treats a continuously moving strip at given locations simultaneously on both sides.

Title: Determination of faults in electrical power transmission links - by monitoring during selected intervals in each half cycle
IPC: H02H3/38
Filed: 1974-07-09
Abstract: The line current (J1) is monitored by a current transformer which, under line fault conditions, may saturate and deliver a distorted output (J2). From this output an auxiliary voltage is derived, by means of unspecified transfer impedances, and the commencement of monitoring periods (t1, t2 ..) derived from its zeros. Preferably the auxiliary voltage is derived by differentiation of the current, such that the zeros are in phase advance of the line current (pref. by about 65 deg., the phase angle of voltage and current at short circuit). A second auxiliary voltage may determine the period length. During at least one period per half cycle faults can be determined by the usual impedance comparison methods.

Title: Carburettor with pressure relief valve for float chamber - has valve actuated by variation in depression near throttle
IPC: F02M5/08
Filed: 1974-11-22
Abstract: The device is intended to overcome the increase in pressure in the float chamber (12) due to the evaporation of fuel in hot weather which causes fuel to flow into the inlet manifold.
